Medical devices have a lower fault tolerance and higher need for traceability because manufacturing defects mean lost lives.

In your example using rusty tools for brain surgery is a good analogy, as it highlights the false dichotomy you've created. A surgeon could also potentially stabilize you for long enough to search for less obviously deadly impliments. Or decide that, rusty tools or not, you're too far gone to help, and divert their attention to people who have a fighting chance.

Emergency doesn't mean we abandon common sense and decide rogue medicine is the only way forward. Even during a time of war, you'd need your tanks to operate as intended, not randomly fire or seal off the interior so tightly it causes suffocation.

This isn't fiddling with your laptop's inner workings. Medicine has a high enough need for precision that doing it poorly, or even forgetting one minor, necessary step in the process will cause more death and suffering than if you had just sat on your hands. The tight regulations are there for a reason. That doesn't mean we need bureaucracy for sake of bureaucracy, but some skeleton regulatory infrastructure will need to be observed for manufactuers efforts to save more lives than it loses.

Rogue medicine is a waste of resources and lives that will only serve to make this situation worse, as will unreliable medical devices.
